T0 at? whom it may concern:

Be it known that 1, Leo K. STAFFORD, a citizen of the United States, residing at Lawton, in the county of Van Buren and State of Michigan, have invented new and useful Improvements in Roller-Bearing Journal-Box Pedestals for Trucks, of which the following is a specifi-' cation,

My presentinvention has reference to a roller bearing journal box pedestal for arch bar trucks. i My primary object is a particular and peculiar construction of pedestals for this purpose whereby roller bearing journal boxes may be easily and quick secured to the arch bar truck and held rmlythereon-in a manner which will permit a limited movement of the box so that the same will be at all times in alignment with the journal.

A further object is the provision of ped-.

estals for the arch bar trucks of roller bearing journal boxes which engage the sides of the journal box in such manner as to positively prevent the lateral movement ranged upon difierent standard sizes of trucks and journal boxes,

A still further object is the production of a device of this character which may be both easily and expeditiously attache to the arch bar frame to positively hold the journal box therein, and which may be likewise as readily removed from the truck shoul occasion reduire.

To the attainment or the foregolng and v other objects which will present themselves as the nature of the invention is better undierstoodreference is to be had to the drawing which accompanies and which forms part of this application.

in the draw1ng:-' I t Figure l is a front elevation of the roller Arch-Bar the subject matter of my U. S. plication, Serial No. 704,822, filed April 7,

Serial No. 721,933.

bearing journal box mounted in an arch bar frame in accordance with this invention.

Figure 2 is a sectional view on the line 2-2 ofFigure 1. i

Figure 3 is a perspective view of one of the pedestals.

My improvement is particularly designed for employment in connection with the type of roller bearing journal boxes which form patent ap- 'Ais disclosedby the drawing, my journal box, indicated by the numeral 1, has its sides formed with longitudinal recesses, and the side walls provided thereby are gradually widenedfrom the ends to the center thereof, as indicated by the numeral 2 (Figure 2). Also the top of the box is centrally formed with enlargements 3 and 4 respectively, there being shoulders 5 provided between the sides andthe enlargements 3 and 4 Also there is a ste portion between the shoulders and the saidenlargement'siiand 4:-

Designed to be received in each of the side depressions of the box 1 is the central straight portion 6 of pedestalsin accordance with my invention. The pedestals are of a width almost equalling the rounded central portions 2 provided the recesses in the sides of the box, and the ends of each pedestal 6 is flanged inwardly, as at 7, the said flanges having their ends received in the referred to notched portions of the enlargements 3 and 4. The ends of the pedestals, however, do not contact with the ends of the said portions 3 and 4.

Resting directly on the upper flanges of the pedestals 5 there is the lower arched bar 8 of the truck, the upper arch bar 9 resting directl upon the lower arch bar. The tie [bar o the frame indicated by the numeral 10 underliesthe lower flanges 7 of the pedestals 6. The arch bars 8 and 9 and the tie bar 10 are provided with aligning openings spaced to accord with the different standard size of arch bar trucks, and, of

course, my improved roller bearing journal box is constructed of different sizes to accommodate the difierent standard sizes oi the arch bar truck. The ends 7 of the pedestal 6 are provided with bolt openings 10. l

@n the inner face of each of the pedestals there is anut 11. These nuts are received outer sides of the pedestals.

.Passed through the referred to openings in the bars of ,the truck frame, and likewise through the openings 10 in the ends of the pedestals and threadedly engaging the nuts 11 are the shanks of bolts 14. The heads of the bolts are, of course, arranged on the outer face of the upper arch bar and on the outer face of the tie bar 10, so it will be noted that when the nuts 11 and the split washers 13 are positioned in their pockets the bolts 14: may be readily screwed to engage the said nuts. The frictional engagement exerted between the angle ends of the pedestals and the nuts will hold the bolts 14 from turning. The nuts 11 cannot turn [because of their ends or facetsbeing disposed in close proximity to the walls provided by the pockets 12. v 7

With my improvement it will be noted that the pedestals may be easily and expeditiously connected to the truck and will efiectively hold the roller bearingjournal box therein. lt will be further noted that the improvement is of an extremely simple construction, and may be cheaply manufactured Also it will be apparent that the bolts 14: cannot only be readily-turned to engage with the nuts but may be likewise easily turned and unscrewed therefrom so that the pedestals may be removed should for any reason it be desired to remove the roller bearing journal box. It is, of course, apparent that the journal box may be positioned by simply removing the outer pedestal, and it is thought that the simplicity and advantages of any construction will be apparent to those skilled in the art to which such inventions relate. I

' Having described the invention, I claim 1. In combination with an arch bar truck and a rollerjournal bearing box to be supported therein, of pedestals between the upper and lower members of the truck and against the sides of the journal box, and

means securing the pedestalsto the truck held in locked position by contacting enthe corners of the journal box and the ,edestals, 1

3. In combination with an arch bar truck, anda roller bearing journal box having 1ts upper and lower portions contacted by the bars of the truck, and said journal boxvhaving its sides recessed, of pedestals between the upper and lower bars of the truck, frame received in the recesses of the sides of the journal box, means removably' connecting, the pedestals to the upper and lower members of the arch bar frame, and means associated with said connecting means received I between the corners of the'journal box and the sides of the pedestals for holding said connecting means in locked position.

i 4. In combination with an arch bar frame and a roller journal boxtherein having its upper and lower edges contacted by the which are in contacting enga ement with the upper and lower bars 0 the frame,

headed bolts passing through the bars of the frame and the angle ends of the pedestals, nuts for the bolts received between and in the path of contact with the corners of the journal box and the sides of the pedestals, and split spring washers around the bolts exerting a pressure between the angle ends of the pedestals and'the nuts.
